+# Single consolidated CI pipeline for PRs. Fires on every PR open/push and
+# runs lint, unit tests, contract tests, and e2e in parallel. The e2e job
+# carries an opt-in SSH breakpoint (label-gated) so maintainers can attach
+# to a wedged sandbox and resume the workflow with `breakpoint resume`.
+#
+# Runner topology:
+#   - lint, unit-test, contract → GitHub-hosted `ubuntu-latest` (ephemeral).
+#   - e2e → self-hosted (needs KVM/large RAM for kind+blockstor sandbox).
+#     Adjust the `runs-on:` label to match the ephemeral runner pool once
+#     ARC / namespace.so / equivalent is wired up.
+#
+# Repository variables (Settings → Secrets and variables → Actions → Variables):
+#   - BREAKPOINT_ENDPOINT (required for the breakpoint step; if unset, the
+#     step is skipped — forks cannot reach the rendezvous server anyway
+#     because variables are not exposed in fork-PR workflows).
+#
+# Labels that change behaviour:
+#   - debug   → opens an SSH breakpoint on e2e failure (paused 20m for first
+#               attach, then 10m idle-timeout after the last disconnect).
